Abstract
"PROCESSO PARA INIBIR A CORROSãO EM UM SISTEMA AQUOSO, E, COMPOSIçãO AQUOSA PARA PRATICAR O MESMO". Processo de utilizar uma composição incluindo cada um ou ambos os isómeros de metil-benzotriazol hidrogenado, a saber, 5-metil-1H-benzotriazol ou 4-metil-1H-benzotriazol, que foram pelo menos cerca de 50% hidrogenados, para formar películas inibidoras de corrosão sobre superficies metálicas em um ambiente aquoso. As composições de metilbenzotriazol hidrogenadas fornecem tanto passivação melhorada como persistência de película aperfeiçoada quando carregadas em sistemas industriais aquosos, em uma base contínua ou intermitente. A dosagem contínua é geralmente mantida em uma constante >0,5, tipicamente 1-2 ppm, no sistema aquoso a ser tratado; doses intermitentes são geralmente de 10-20 ppm uma vez por semana ou duas ou mais. Além das características aperfeiçoadas descritas acima, as películas formadas da composição inventiva também reduzem o bloqueio das taxas de corrosão imediatamente em seguida a adição de halogênio; retorno mais rápido sustentado para taxas de corrosão pré-halogenação pós-halogenação; e reduzem a taxa de conversão de fosfonato em ortofosfato, o que reduz o potencial de crosta. Por estas razões, as presentes composições são continua ou intermitentemente alimentadas e eficazes para inibir a corrosão do cobre e das superfícies de liga de cobre sujeitas a sistemas aquosos alcalinos, neutros ou ligeiramente acídicos."PROCESS TO INHIBIT CORROSION IN A WATERFUL SYSTEM, AND, WATER COMPOSITION TO PRACTICE THE SAME". Process of using a composition including each or both of the hydrogenated methyl benzotriazole isomers, namely 5-methyl-1H-benzotriazole or 4-methyl-1H-benzotriazole, which were at least about 50% hydrogenated, to form films corrosion inhibitors on metallic surfaces in an aqueous environment. The hydrogenated methylbenzotriazole compositions provide both improved passivation and improved film persistence when loaded into aqueous industrial systems, on a continuous or intermittent basis. The continuous dosage is generally kept at a constant> 0.5, typically 1-2 ppm, in the aqueous system to be treated; intermittent doses are usually 10-20 ppm once a week or two or more. In addition to the improved characteristics described above, the films formed from the inventive composition also reduce the blocking of corrosion rates immediately after the addition of halogen; faster sustained return to post-halogenation corrosion rates; and reduce the rate of conversion of phosphonate to orthophosphate, which reduces the crust potential. For these reasons, the present compositions are continuously or intermittently fed and effective to inhibit corrosion of copper and copper alloy surfaces subject to aqueous, alkaline, neutral or slightly acidic systems.
